The `needs_cleanup` flag needs to be set per-module when an exploit
needs an interactive session to clean up. Some `FileDropper` exploits
need additional cleanup to what the mixin provides, but since all
`FileDropper`s already mark themselves as needing cleanup those are not
covered here. A few of these could potentially be refactored to use the
original exploitation method to clean up or to compile the list of
files/commands to clean up ahead of time, but that is out of the scope
of this fix.
See the complaint on #4039. This doesn't fix that particular
issue (it's somewhat unrelated), but does solve around
a file parsing problem reported by @void-in
According to the Ruby style guide, %w{} collections for arrays of single
words are preferred. They're easier to type, and if you want a quick
grep, they're easier to search.
This change converts all Payloads to this format if there is more than
one payload to choose from.
It also alphabetizes the payloads, so the order can be more predictable,
and for long sets, easier to scan with eyeballs.
